A brave New York City cop who saved dozens from falling debris on 9/11 will be honored in London tonight.

When the South Tower collapsed, Lt. Timothy McGinn and about 30 people ran to a nearby building for safety. As flying debris began to pelt them, McGinn shot out one of the building’s windows with his service revolver, allowing the group to escape.

“He saved my life and I was able to continue to document the horrific events of that day,” said freelance cameraman Joseph McCarthy.

McGinn, the commanding officer at Pier 40, is being given the Freelancer’s Choice award by the Rory Peck Trust, a charity that trains and supports freelance photographers.
